Java Help Wanted Vexes keep spawning (lemon iced raid farm)

Thumbnail gallery
Upvotes

Im not entirely sure on how this farm works, so if anyone can explain that to me I would be grateful. Besides that, when I try using the farm in creative it works just fine. However, once I finish the build and used it, they started to spawn. I looked at the blocks that were marked as red/orange by litematica, but it was mostly redstone dust for the sorter. Initially, I thought the problem was the killing chamber so I redid that carefully. The problem still occurred. I also thought that it could be the mobs (allays) I replaced. But I tried it in creative, just pasted the farm and replaced the pillagers and worked just fine. Could it be line of sight? It seems like mobs can still see me through glass.

Java Help Wanted Carpet duper

Post image
8 Upvotes

I have a carpet duper, and this is a problem that keeps occuring. It's an auto smelter, and I have a comparator at the bottom output hopper to check when items complete, and trigger the carpet duper. AND I have the hoppers leading into a dropper that drops the extra into lava to prevent over flowing. But the carpets keep catching the duped ones on them. How do I keep this from happening?

Java Help Wanted What itemsorter should I use?

1 Upvotes

I'm looking for an automatic storage system for my Minecraft world, but I'm not sure which design would fit my needs best.

I want a single-item sorter that can eventually handle around 500 different items (although realistically I will probably only need around 350–400). I don't really like multi-item sorters, because I find them harder to organize and understand.

Performance is also a big concern for me. I don't want to use copper golems or other entity-heavy solutions because I'm playing on a potato PC, so I need something that is as lightweight as possible. Water streams would be completely fine if they are still considered a good performance-friendly option.

The system would ideally start with a shulker box unloader and then sort everything into storage.

My dream setup would be something where the storage uses shulker boxes in a modular way. For example, the shulker boxes would already be placed as the active storage, even if they are not completely full yet. Once a shulker box is full and more items come in, it could be moved into a normal storage area, and when I need the storage module again, the shulker box could be placed back automatically. Basically, I like the idea of having storage modules that I can remove and move around with a button instead of having a permanently fixed storage wall.

It doesn't have to be the fastest system possible. I care more about it being reliable, expandable, reasonably cheap, and not too demanding on performance.

What sorter design would you recommend?

I found this video about a cool villager swapper that could hold 23 villagers in a cell, but it was sadly broken in 1.20 because of changes to honey blocks. Is there any way to modify to make it work again?

Rule-8 Compliant A mod I've been working on that integrates Git with Litematica.

I just wanted to share a passion project I've been working on with u/scorpio_03 for the past 2 months in case others were interested. It's a fork of litematica that adds a bunch of features on top of it which allows to easily manage and share tons of changes on a project.

It has all the important stuff like creating commits, branching for safely exploring an alternative direction with your project, and even basic merging with merge conflict handling. In the backend, it stores a real git repository so you can push/pull your project and commits with platforms like github.

I initially made this for myself and a few friends since, especially for technical builds like tree farms, we are addicted to exploring different layouts and making tons of optimizations to the wiring, etc. At the end of it, we are left with over a hundred different schematics of our project which is not fun to manage by hand at all and figure out the changes.

It’s still in early development and the core workflow is starting to come together, so I wanted to share what I had and see what people think for those who are interested!

Java Help Wanted Wither obsidian farm (1.21.11) — snow golem snowballs won't hit the Wither, no obsidian breaking

0 Upvotes

Hey all, hoping someone can sanity-check my setup or confirm a known issue.

I'm running a wither obsidian farm in the End (similar to the "32,000 obsidian/hour" style tutorials) — Wither is caged on the obsidian platform, not moving, and I've got a snow golem set up in a poke-hole to hit it with snowballs so it goes into the charged/blue-skull phase and starts breaking obsidian.

Problem: the golem's snowballs just aren't connecting with the Wither. Wither stays at full/near-full health, no charged skulls, no obsidian breaking. I've confirmed:

  • The Wither isn't moving.
  • The poke-hole/line of sight looks clear to the Wither's body.
  • Golem appears to be in position per the tutorial.

I found an old bug report thread describing this exact issue — golem randomly stops being able to hit its target even in an otherwise working farm, with the only fix being to break and replace the golem. I also saw a YouTube comment on a relevant tutorial (on 1.21.11) saying the workaround is to skip relying on the golem entirely and just use a dispenser loaded with snowballs, fired via redstone clock, aimed straight at the Wither.

I'm now building that: dispenser next to the Wither, wired to a simple 2-repeater clock loop for continuous firing.

Questions for the hive mind:

  1. Is the golem-not-hitting-target issue still a known bug on 1.21.11, or is this version-specific/newer?
  2. Anyone had good results switching fully to a dispenser instead of a golem for damage in these farms?
  3. Any gotchas with wither skulls/explosions damaging the redstone clock circuit near the dispenser that I should watch for?

Appreciate any input — first time building one of these and want to make sure I'm not missing something obvious before I fully commit to the redstone.

You just have to set "forceBlend" NBT in your chunks to true, and "transplant" them into your old world after clearing some buffer area chunks to grow the incoming biome. Here are some pics.

My main use case for this would be stacking totems.(put 2 enchanted totems into grindstone, 2 will come out stacked) I'm also not against version switching or the use of mods to block packets or something.
